Description

Protective sheet for body-worn devices and body-worn devices including the same {PROTECTIVE SHEET FOR ON-BODY TYPE DEVICE AND ON-BODY TYPE DEVICE HAVING THE SAME}

The present invention relates to a body-attached device, and more specifically, to a protective sheet for a body-attached device that covers and protects an adhesive layer provided on the body-attached device so that it can be attached to the user's skin, and to a body-attached device including the same. .

Recently, with the advancement of medical technology, various body-attached devices that are attached to the user's body have been developed and sold. Body-worn devices can be usefully attached to the body of a chronic disease patient to monitor biometric information or provide treatment.

For example, chronic diseases such as diabetes require continuous management, and body-worn devices can be used to manage blood sugar levels in diabetic patients.

Diabetes is characterized by almost no noticeable symptoms in the early stages, but as the disease progresses, symptoms characteristic of diabetes include diarrhea, polyphagia, polyuria, weight loss, general malaise, itchy skin, and cases where wounds on the hands and feet do not heal and persist for a long time. appears. As diabetes progresses further, complications such as vision impairment, high blood pressure, kidney disease, stroke, periodontal disease, muscle spasms, neuralgia, and gangrene appear.

In order to diagnose diabetes and manage it to prevent it from developing into complications, systematic blood sugar measurement and treatment must be carried out together.

For diabetic patients and people who have not developed diabetes but have more sugar than normal detected in their blood, many medical device manufacturers provide various types of blood glucose meters that can measure blood sugar.

There are two types of blood glucose meters: one where the user collects blood from the fingertip and measures blood sugar on a one-time basis, and one where the user attaches it to the user's stomach or arm and continuously measures blood sugar.

In the case of diabetic patients, they generally go back and forth between hyperglycemia and hypoglycemia. Emergency situations occur during hypoglycemia, and loss of consciousness or prolonged hypoglycemia without sugar supply can result in death. Therefore, immediate detection of hypoglycemia is very important for diabetic patients, but blood glucose meters that measure blood sugar intermittently have limitations in accurately detecting this condition.

Recently, to overcome these limitations, a continuous glucose monitoring system (CGMS), which is inserted into the human body and measures blood sugar levels at intervals of several minutes, has been developed and used. In order to minimize the user's pain and resistance to blood collection, the continuous blood sugar measurement system can measure blood sugar continuously after inserting a needle-shaped sensor into areas where pain is relatively less, such as the stomach and arms.

The continuous blood sugar measurement system includes a sensor that is inserted into the user's skin to measure blood sugar, a transmitter to transmit the blood sugar level measured by the sensor, and a terminal that outputs the received blood sugar level. The sensor is combined with a transmitter to form a body-worn device that wirelessly transmits biometric information to a terminal, etc.

The body-worn device of the continuous blood sugar measurement system has an adhesive layer and is attached to the user's skin by an applicator and can measure the user's blood sugar level for several days to tens of days. The adhesive layer of the body-worn device is covered and protected with a protective sheet, and the protective sheet is removed before the body-worn device is attached to the user's skin.

Generally, a body-worn device of a continuous blood glucose measurement system is provided to a user assembled in an applicator. Therefore, in order to operate the applicator and attach the body-worn device to the user's skin, the protective sheet covering the adhesive layer of the body-worn device must first be removed.
